• Increased solar activity – glancing blow possible on January 19

    ByTeo Blašković

    Solar activity reached high levels in the past 24 hours, with the strongest event being an M6.0 flare from Region 3191. This event was accompanied by a Type II radio sweep and a Coronal Mass Ejection (CME) signature, however, analysis and modeling indicate that no Earth-directed component was produced. A CME was also observed off the southwest limb at 22:00 UTC on January 14, with analysis and modeling suggesting the possibility of a glancing blow on January 19.

  • Cosmic rays decreasing as Solar Cycle 25 gains strength

    ByTeo Blašković

    New data provided by the students of Earth to Sky Calculus and Dr. Tony Phillips of SpaceWeather.com show that cosmic radiation levels in the Earth's atmosphere are decreasing as the new solar cycle — Solar Cycle 25 — gains strength. The plot below shows…

  • Solar filament eruption, possible glancing blow on November 29

    ByTeo Blašković

    A solar filament was observed lifting off the Sun's northeastern quadrant beginning at approximately 04:45 UTC on November 25, 2017. An associated weak Coronal Mass Ejection (CME) was observed in SOHO/LASCO C2 and C3 imagery and the analysis shows a potential…

  • Remarkable pink aurora outburst over Norway

    ByTeo Blašković

    Over the past couple winters, big displays of pink and white auroras have coincided with spotless suns. The sight is often big enough to make observers wonder if there is a connection, SpaceWeather reports. The most recent remarkable outburst of pink auroras was…

  • Extreme space weather event that could have led to a nuclear war

    ByTW

    For the first time, retired U.S. Air Force officers involved in forecasting and analyzing the extreme space weather event of May 23, 1967, collectively and publicly describe how great solar and geomagnetic storm at the height of the Cold War almost led to a…

  • Robust CME simulation model developed for future of space weather forecasting

    ByTW

    Japanese scientists have developed a new and robust simulation code for Coronal Mass Ejection (CME) events based on the realistic description of the mechanisms behind their generation and propagation through space. The method has been successfully validated using…

  • Using maths to reveal the Sun’s magnetic field mysteries

    ByEgert Indres

    An important research project, led by the UK's University of Dundee, aims to improve knowledge of Sun's complex magnetic fields using mathematics. The goal is to find out the effects of space weather caused by the Sun and its magnetic structures origins….
